in the circuit of Figure 1
Specifications in
boldface
apply over the full rated temperature range.
Note 2:
Thermal resistance of the TO-46 package is 400C/W, junction to ambient, and 24C/W junction to case. Thermal resistance of the TO-92 package is
180C/W junction to ambient. Thermal resistance of the small outline molded package is 220C/W junction to ambient. Thermal resistance of the TO-220 package
is 90C/W junction to ambient. For additional thermal resistance information see table in the Applications section.
Note 3:
Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating effects can be com-
puted by multiplying the internal dissipation by the thermal resistance.
Note 4:
Tested Limits are guaranteed and 100% tested in production.
Note 5:
Design Limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage ranges. These limits are not used to cal-
culate outgoing quality levels.
Note 6:
Specifications in
boldface
apply over the full rated temperature range.
Note 7:
Accuracy is defined as the error between the output voltage and 10mv/C times the device’s case temperature, at specified conditions of voltage, current,
and temperature (expressed in C).
Note 8:
Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the device’s rated temperature
range.
Note 9:
Quiescent current is defined in the circuit of Figure 1
Note 10:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC andAC electrical specifications do not apply when operating
the device beyond its rated operating conditions. See Note 1.
Note 11:
Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 12:
See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in a current National Semicon-
ductor Linear Data Book for other methods of soldering surface mount devices.
